y, This invention'relates tobo'oks, and more particularl'yfto a book especially adapted fork persons Who deliver public'readings to havev such'a collection ina permanently bound book.'r This is objectionable in that, of a col- 15 lection ofa number of articles-or stories, but onev or twomay be suitable for the'use ofthe reader.V In the teachingof `dramatics and yin`public reading",r asa general rule, `the instructor or reader uses one or several ar- 1`-20 ticles l'or storiesvvhich are particularly suitable for the 'subject underconsider'ation o1' i lforthe purpose fonwhi'ch ythe-readingiis s c Toloeatefthese' selectionsina permanently bound volume containing many 25 other.selections:`wl1ich thev reader does not fisc or storiesfor 'the sole purpose of Vacquiring but one'or -tWostories vwhich the readerisv desirous lof using'. To avoid'this'objection 'y hasgbeen proposed to'pnblishshort stories'or articles for use by publiek readers inpam- '535.1 phlet4 form.l `These pamphlets orY booklets can be placed in ay suitable binder and arranged in any desired orderfsoy as tobe avail- I able. The objection to this practicefis that o the'fpan'iphlets are bound 1 separately land 140 When placed in av binder to/form a series or cllection, difficulty is experienced 1n kquickly turning the leaves of the; individual pam# phlet or booklet. f c' l v I 'have found that the above objections to 45 the present practice can be overcome by providi'ng` a" booklet which contains vone subject or story andr Which is so assembled that, preliminary to y'placin'gthe booklet ina loose leaf binder, vthe leaves ofsuch booklet can be 50 readily separated so thatywhenfa'plurality of these booklets are mounted in a'y loose leaf binder they formv a'truly loose leaf collection, v thel individual leaves ofvvhichmaybe read ily turned and yet theleaves vare properly grouped 'so'thatlthose relating'to one's'ubject 55 matter orv one story are arranged together in proper sequence,the various groups being separatedby suitable title pages' indicating thetitle orL subjectmatter ofthe respective groups, which originally Aformed* the indi- 60 vidual booklet. y To accomplish this `result I temporarily bindV or secure together the leaves, y including the coverv sheets of the individual'- booklets in what I term tearable manner, ythat-is, in Asuch amanner that theA 65 bound portions ofthe leaves vmay be readily Y torn Sofi?, 'thus' leaving the leavesseparate fromreach other. These booklets are preferably suitably perforated to be inserted into a'loose leaf-'binder of suitable type: Further irc objectsand advantages of my inventionvvill appear from the detail description.

cent the line of sewing andy disposed between the line of sewing and the free edges'of the leaves, the portions of vthe leaves :between the line of sewing and the free edges ofthe leaves being otherwise free of perforations or openings which would tend to weaken them.

2. As a new articleL of manufacture, a booklet comprising a plurality of 'leaves vformed from single sheets folded upon themselves, the leaves being secured together by aline of sewing extending'along the Jfold of .the booklet andthe holes made by the sewing providing a line offclose perforations which facilitates yready separation of the leaves by tearing along the', line of sewing, said line .of sewing constituting the sole means for securing thel leaves together, each sheet being provided with openings at opposite sides of the lineV of sewing adapted for 'Y Yreception of securing elements of a binder for binding together all of the sheets as a unit after tearing apart thereof `and in at- Vwise relation, all of the leaves being otherc wise free from yperforations or openings which would tend to yweaken them.
